- no
- Conclusions:
- The test item Imidazolhydrobromid has a melting range of 220.3 °C to 225.7 °C.
Reference
The determination of the melting point was performed by visual judgement using the capillary method. The test item showed five stages of melting. the melting starts at 220 °C and ends at 226 °C. No solid particles were left.
